Validating the configuration of a logical partition before the migration operation

You can use the validation function on the Hardware Management Console (HMC) to validate the configuration of a logical partition before starting the migration operation. If you are using HMC V9.1.940, or later, and when the firmware is at level FW940, or later, you can validate a logical partition that is configured with Single Root I/O Virtualization (SR-IOV) logical ports.

About this task

To validate the configuration of a logical partition before starting the migration operation, complete the following steps:

Procedure

  1. In the navigation pane, click the Resources icon The icon represents the Resources function of the HMC.
  2. Click All Partitions. Alternatively, click All Systems. In the work pane, click the server name that has the logical partition.
  3. Click View System Partitions. The All Partitions page is displayed.
  4. In the work pane, select the logical partition and click Actions > Mobility > Validate. The Partition Migration Validation window is displayed.
  5. Follow the steps in the Partition Migration Validation window.
  6. You can use the Only migrate SR-IOV logical ports when possible option to validate or migrate a logical partition that is configured with SR-IOV logical ports.
    • When the Only migrate SR-IOV logical ports when possible check box is enabled, the HMC performs the following task:
      • The HMC fails the validation or migration operation if the HMC cannot find an SR-IOV physical port to re-create any of the source SR-IOV logical ports that are migratable before the client logical partition is moved to the destination system.
      • If the client logical partition is already moved to the destination system and if the re-creation of the migratable SR-IOV logical ports on the destination system fails, the HMC does not move the client logical partition back to the source system. You can dynamically add the migratable SR-IOV logical ports on the client logical partition after the migration operation completes.
    • When the Only migrate SR-IOV logical ports when possible check box is disabled, the HMC performs the following task:
      • The HMC does not fail the validation or migration operation even if the HMC cannot find an SR-IOV physical port to re-create any of the migratable SR-IOV logical ports on the source system. Also, the HMC does not attempt to re-create those SR-IOV logical ports. You can dynamically add the migratable SR-IOV logical ports on the client logical partition after the migration operation completes.
    Note: When the HMC is at Version 9.1.940.x, and when the firmware is at level FW940, the Migratable option for the Hybrid Network Virtualization capability is available as a Technology Preview only and is not intended for production deployments. However, when the HMC is at Version 9.1.941.0, or later, and when the firmware is at level FW940.10, or later, the Migratable option for the Hybrid Network Virtualization capability is supported.
  7. Complete the steps in the Partition Migration Validation window, and click Validate.
  8. If the validation operation fails, the Validation Errors/Warnings window is displayed that helps you to troubleshoot the configuration problems.
    • Click All Messages to view the warnings and error messages along with the verbose log information about the validation operation. The log information also includes data about successful and failed steps.
    • Click Step Results to view the log information about the validation operation. The log information also includes data about successful and failed steps.
